Volatility is the nature of the biotech beast, and it must be tamed or utilized to advantage. That's the philosophy of Eden Rahim, portfolio manager and option strategist at Theta Strategies Capital. Can you grow a portfolio if some of your more successful names are called away by option buyers before the stock goes into the stratosphere? The answer is yes, and in this interview with The Life Sciences Report, Rahim describes his technique and leaves readers with six names that he fully expects to reap very large gains.

The Life Sciences Report: You are CEO and cofounder of Theta Strategies Capital, and also the portfolio manager and innovator of the Next Edge Theta Yield Fund, which derives income from the options strategies you have developed over two decades. These strategies profit, in part, from the decline in pricing that occurs as options approach expiration. Could you describe that strategy?

Eden Rahim: Yes. My partner, Mike Bird, and I formed Theta Strategies Capital a couple of years ago to provide institutions with income and hedging solutions using option strategies as an advantage. We thought we would be able to add yield to institutional portfolios, dampen volatility and protect against downside. We have designed and traded a variety of strategies through virtually every crisis in the past couple of decades.

In January, we launched a prospectus fund called the Next Edge Theta Yield Fund. Essentially, what we do is exploit the mathematical property of all options to lose value with the passing of time. That property is called theta. If you own an option, it loses a little bit of value every day, regardless of the underlying security or index. We first conceived of this fund back in 2002, and thought of it as a novel way to provide yield. Bond investors are always trying to pick the best income funds. We created a yield product that exploits strategies option market makers use, and we brought that to average investors through this prospectus-based fund.

TLSR: So, at least with your income fund, you don't care which way the market is going?

ER: No. Our mandate is agnostic. We don't rely on forecasts and market direction. We're not trying to predict whether the market will go up or down, as a traditional fund would do. We know the market is going to do whatever it wants to do. We can't control that. The Theta Yield Fund basically holds 90–95% cash, and we invest in limited-risk option spreads that exploit time to expiration.

TLSR: As simply as possible, give me an example of how writing an option works for you.

ER: Sure. We use a variety of risk-defined strategies, one of them being a call calendar, for example. Let's say the S&P 500 is sitting at 2,100 right now. A one-month call option trades at about $25, and it loses value, or decays, about $0.60 a day. A two-month option with a 2,100 strike price costs $40, or 60% more, but that option loses only $0.40 a day. So the longer-dated option loses less value each day than the shorter-dated option. If you short the one-month option at $25 and buy the two-month option with a 2,100 strike at $40, it costs you $15, but with the whole position, you benefit by a gain of $0.20 a day. You're not making a market call because you're long and short at the same strike price. All you're doing is exploiting that property of options to lose value, and you benefit from it. Again, exploiting that property is what we call a theta strategy.

TLSR: Why do you hold so much cash in the Theta Yield Fund?

ER: We only write premiums equal to 2–3% of the net asset value (NAV) of the funds because we're not there to hit home runs. We're just trying to hit singles for average. We want to have very low volatility. We want to be agnostic to market changes.

We could obviously have higher returns. The goal is to earn about 0.5% to 1% per month, with very low volatility. If we do that, the fund earns its stripes.

TLSR: Let's talk about your Bio-Tech Plus Fund. It's a growth fund. Do you hedge this fund? You limit your upside that way, don't you?

ER: Yes. That's a great point. I do hedge the portfolio. And that does, at times, limit the upside of the portfolio, but with the key ancillary benefit that it also limits the downside exposure. You and I both know that with biotech, it can be up by the escalator, then down by the elevator at times. During this five-year bull, in 2010, 2011 and 2013 we had 15% corrections, and in 2012 and 2014 we had 25% corrections. And yet the bull goes on. It's just par for the course in the sector. Even this year, in March and April we had 10% selloffs from the peak to the trough, all within this bull move. That's just natural to biotech. We accept it for what it is, and we take steps to dampen that volatility because we're counting on stock picking to deliver our returns.

One of my holdings is Inotek Pharmaceuticals Corp. (ITEK:NASDAQ). It's up more than 100% in a very short period, and that one position adds about 1% return to the fund. I rely on stock picking for excess returns, and then I try to dampen the sector volatility with hedges and written calls. That's the philosophy behind it.

TLSR: Eden, you have some stocks in the Bio-Tech Plus portfolio that range from $20 million ($20M) to $60M in market cap. These are true micro-cap stocks. You also have some small caps, in the $200–300M range. But you can't write options on the very small names, can you?

ER: No. Most of the options we have written are in the mid-cap area. I've written calls against Acadia Pharmaceuticals Inc. (ACAD:NASDAQ), Amicus Therapeutics Inc. (FOLD:NASDAQ), Halozyme Therapeutics (HALO:NASDAQ), Portola Pharmaceuticals (PTLA:NASDAQ), Raptor Pharmaceutical Corp. (RPTP:NASDAQ), Supernus Pharmaceuticals Inc. (SUPN:NASDAQ) and Synergy Pharmaceuticals Inc. (SGYP:NASDAQ). They're in the $1–2 billion ($1–2B) range. Each of those are roughly 1.5–2% weights in the fund. And they have all had big moves. I'm trying to hold them for the long term, but when they get extended and move far above their moving averages in a short period of time, as some of them have, I will write options.

Every once in a while you miss it and a company might move higher, like Ultragenyx Pharmaceutical Inc. (RARE:NASDAQ). I sold options on my Ultragenyx position at $100 after it moved up from $54, but it then went to $127. It was crazy. I did leave some upside on the table there, but you don't know these things in advance. Ultragenyx could just as well have fallen back to $90 or $85.

Over time, options just add an extra form of defense for our unit holders because nothing grows to the sky. When these stocks move far above their 50-day moving averages, I'll write the options.

TLSR: Your Bio-Tech Plus Fund invests in small- and mid-cap Canadian and U.S. biotech companies, as well as some specialty pharmas. My understanding is that over nine years, from 1995 to 2003, you achieved a 26% annual compounded rate of return in a biotech mandate at RBC. You are obviously seeking and achieving growth. If you had to narrow it down, what handful of critical principles should investors adhere to when investing in small-cap biotech stocks?

ER: I think the first principle is to have a healthy respect for the volatility of the biotech sector, and to find ways to use that volatility to your advantage. It's going to be there anyway, so try to make volatility your friend.

A second principle would be to reduce complexity by following a proven discipline. It doesn't have to be mine; everyone can find their own. Not straying too far is the key. My discipline is to focus primarily on midstage companies that report efficacious data from well-designed, controlled trials where the data are peer-reviewed. That's my wheelhouse. I tend not to play overwhelmingly in the preclinical or Phase 1 stages. My exception is that I do play in early-stage regenerative medicine and central nervous system (CNS) indications.

I also rely heavily on key opinion leaders (KOLs), paying attention to what they say about a drug and how it's going to be adopted by physicians and patients. This is one way to reduce complexity, and is very important.

A fourth principle might be to watch what the big money is doing. What technologies are big biotech and big pharma spending on? I try to watch the Genentechs (a unit of Roche Holding AG [RHHBY:OTCQX]), the Amgens (AMGN:NASDAQ), the Biogens (BIIB:NASDAQ), and so on. They have enormous, limitless resources with which to look at molecules, receptors, target sites and mechanisms of action. See what they're doing, and then find the smaller companies working on something similar.

If I could suggest a fifth principle, it would be to focus on companies that, even though they may be in midstage development, have identified a path to profitability. I've seen too many companies get through the approval process and never make money. Perhaps they developed a me-too drug with too small a market, or something like that. The path to profitability has not been mapped out, and the company just burns capital.

TLSR: What is the most favorable environmental factor for biotech today? Is it the technicals? Is it regulatory? Is it the group of new technologies—immune checkpoints, gene and cell therapies, antisense—that are going to feed pipelines for the next two decades?

ER: The new technologies are certainly drivers. There have been revolutionary advances. Illumina Inc. (ILMN:NASDAQ), for example, was able to take the cost of sequencing a genome down from $2.7B to $10,000 ($10K), and that's now down to about $1K. We're seeing a technology revolution in biotech enabled by enormous computing power. Our understanding of protein folding right now, for instance, is revolutionary. What CRISPR (clustered regularly interspaced short palindromic repeats) is doing to gene editing is revolutionary. A genome can be edited now in any location. These are drug discovery tools that never existed before, and the increase in scale has been exponential. The technology revolution is one of the underpinnings.

The regulatory environment is another area where things have changed. The FDA started issuing breakthrough designation statuses, generally for rare indications with high fatality rates. Then another group of companies began developing drugs for very narrow populations, and their costs of capital plummeted because the barriers to approval and commercialization went way down. There was also a whole group of initial public offerings that came of age in 2012, 2013 and 2014, and some of these have soared.

It's going to be there anyway, so try to make volatility your friend."

I think the stock and biotech index charts showing the multiyear biotech breakouts are capturing the spirit of what's going on collectively in the space. They confirm that we're in a secular bull market—probably a decade-long bull at a minimum—and it is behaving in a very orderly fashion. Lots of people have stood on the sidelines and not participated in it. They've been calling it a bubble because they remember 2000. I remember 2000 well, and I remember 1992 well, and I remember 1983 well. This is not that. There is something unique happening here, and there's a fundamental basis for it.
