If you're in the bull camp on WFR, then I would look for long-biased trades once this stock manages to break out above some near-term overhead resistance levels at $2.59 to $2.69 a share, and then once it takes out its 200-day at $2.85 a share with high volume. Look for a sustained move or close above those levels with volume that registers near or above its three-month average action of 4,373,750 shares. If that breakout triggers soon, then WFR will set up to re-test or possibly take out its next major overhead resistance levels at $3.35 to $3.77 a share.

The last name to consider with some huge insider buying is biotechnology and drugs player Genomic Health ( GHDX). This company is engaged in the development and commercialization of genomic-based clinical laboratory services that analyze the underlying biology of cancer, allowing physicians and patients to make individualized treatment decisions. Insiders are buying this stock into some recent weakness, since shares are down by over 20% in the last three months.

Its estimated growth rate for this year is -19.2%, and for next year it's pegged at 57.1%.

A director and beneficial owner just bought 926,939 shares, or around $25.72 million worth of stock, at $25.83 to $27.99 per share.

From a technical perspective, GHDX is currently trending well below both its 50-day and 200-day moving averages, which is bearish. This stock has been downtrending for the last two months, with shares falling from a high of $36.83 to its recent low of $25.25 a share. During that downtrend, shares of GHDX have been consistently making lower highs and lower lows, which is bearish technical price action. Shares of GHDX also gapped lower during that timeframe from around $32 to $25.25 a share with huge selling volume. That said, the stock has started to stabilize and move within range of triggering a near-term breakout trade.
