Let’s first take a step back and analyze how tracking hedge funds can help an everyday investor. Through our research we discovered that a portfolio of the 15 most popular small-cap picks of hedge funds beat the S&P 500 Total Return Index by nearly a percentage point per month on average between 1999 and 2012. On the other hand the most popular large-cap picks of hedge funds underperformed the same index by seven basis points per month during the same period. This is likely a surprise to many investors, who think of small-caps as risky, unpredictable stocks and put more faith (and money) in large-cap stocks. In forward tests since August 2012 these top small-cap stocks beat the market by an impressive 66 percentage points, returning over 123% (read more details here).

Aquinox Pharmaceuticals Inc. (NASDAQ:AQXP) is a clinical-stage pharmaceutical company that aims at discovering and developing targeted therapeutics in disease areas of inflammation and immune-oncology. The company’s lead drug candidate is AQX-1125, which is a small molecule activator of SH2-containing inositol-5′-phosphatase 1 (“SHIP1”) and has demonstrated broad anti-inflammatory activity. The stock is one of the top gainers today, jumping by more than 250% in intraday trading on the back of positive results from AQX-1125 trial, while year-to-date, the stock has advanced by some 400%. Another shareholder that will most likely profit from the stock’s surge is another healthcare-focused fund Kevin Kotler’s Broadfin Capital, which owns 531,768 shares as of March 31.

Let’s now discuss in more detail the extent to which the positive results from the clinical trial might influence the company’s success in the future. It’s worth mentioning that analyst Biren Amin from Jefferies has recently downgraded the rating on Aquinox to “Hold” from “Buy” and reduced the price target from $13 to $2 after the company’s flagship trial of AQX-1125 in chronic obstructive pulmonary disease patients with frequent exacerbations failed to demonstrate efficacy. Nevertheless, Aquinox has just announced consistently positive results from secondary endpoints from its Phase 2 LEADERSHIP trial with AQX-1125 in patients with bladder pain syndrome/interstitial cystitis (BPS/IC) and the stock skyrocketed on Monday. Hence, there are only a few steps remaining for AQX-1125 in BPS/IC towards its commercialization. The healthcare company intends to finalize its pivotal trial designs in consultation with the U.S. Food and Drug Administration and the European Medicines Agency so as to set a path for the potential approval. Eventually, as soon as the company’s lead candidate is approved, a new flourishing revenue stream unlocks for Aquinox.

Meanwhile, the company’s financial results are weak, which is not surprising for a clinical-stage company. As of the end of June, the company has cash and cash equivalents of $29 million, down from $41 million a quarter earlier, and it posted a net loss of $4.8 million for the second quarter, slightly narrower than a loss of $5.4 million a year earlier.
