 Insiders recently got a bad rap, as the Feds levied charges on Senator Richard Burr for illegally using information from a closed Senate hearing to avoid a loss in his stock transactions. It was a classic abuse situation, and one that Federal securities regulators work hard to prevent.But there are always people in the know, and its only human nature for them to use their knowledge in their trades. These insiders are corporate officers and board members, and theyre charged with running their companies profitably for the benefit of shareholders. Its accepted that theyll use their info in their trading, as they almost always own considerable blocks of shares to keep the playing field level, these insiders are required to publish their transactions every quarter.And the trading public can use those disclosures to plot an investing strategy. Using the TipRanks Hot Insiders Stocks tool, you can see which equities are the target of insider moves, whether those moves are buys or sells, and whether they are informative or simply adjustments to a holding. Weve pulled up three stocks that have shown recent Informative Buys from their corporate insiders. Here are the details.FlexShopper, Inc. FPAYWe will start with an interesting stock. FlexShopper is an e-commerce company, with subsidiaries that operate a lease-to-own online marketplace. Products available include electronics, video games, furniture and home appliances, musical instruments, and health and fitness gear.The company reported at 8.8 gain in net revenue in Q1. Where most companies took a hit due to the coronavirus crisis, e-commerce was one of the few sectors that saw continued opportunities.Despite the strong quarterly performance, FPAY shares are down 33 year-to-date. In fact, the share price has slipped down to penny-stock territory, a niche that offers both low prices and high upside potential for investors willing to take on some risk.The insiders at FlexShopper are clearly willing to do just that. For the last three months, no fewer than four company officers have been making informative buys of FPAY stock. The largest purchaser, Howard Dvorkin, a board member of the company, spent 954,000 on more than 600,000 shares. Other inside purchasers include Richard House, who bought 48,000 shares for 60,000, and Scott King, who in March bought 25,000 shares for 44K.Ascendiant analyst Theodore ONeill sees a clear path forward for FPAY. He writes, We believe the current horrendous macro-environment could be a big positive for FPAY. Looking at recovery from the last great recession, and in particular looking at the stocks of companies that sell tires and mattresses, where FPAY has good exposure, those stocks rose 2x-3x off the bottom in the first year... We believe the addressable market for FPAY is at least 25 billion. The market is for sub-prime borrowers and those without access to conventional credit, however it isnt limited to that segment and could diversify further.ONeill gives FPAY a 5 price target, implying an upside of 203 for the coming year. To watch ONeills track record, click hereThere are only two reviews on record for FPAY shares, but both are Buys. The stocks trading price is 1.65 and the average price target is 4.25, which shows the rich potential in penny stocks the upside here is an impressive 151.

The companys shares are down 44 in the overall bear market, serious underperformance compared to the SP; 500. At the same time, quarterly net investment income was up 21 to 58.44 million. The company did defer its dividend payment in the current quarter not a positive move, but a cautious play that maintains cash reserves in a time of crisis.The insiders, however, clearly like this stock. Over the past three weeks, CEO Christian Oberbeck, CFO Henri Steenkamp, and board member George Cabell Williams have all made sizable purchases. Oberbecks buys have totaled over 320,000, which he spent on 24,000 shares. Williams bought 12,000 shares for 154,000, and Steenkamp picked up 2,000 shares for 26,000. These purchases have put a positive spin on the SARs insider sentiment.Analyst Timothy Hayes, of B. Riley FBR, reiterated his Buy rating and maintained his 21 price target on the stock. His target implies a robust upside of 36 in the coming 12 months. To watch Hayes track record, click hereBacking his rating, Hayes noted the serious move to defer the dividend: ...we believe SAR is being overly conservative with the decision, and is aiming to preserve as much liquidity as possible in anticipation of bear case scenarios. We do not view the dividend deferral to reflect a deterioration in credit or earnings power, as nonaccruals remain low as of May and we believe SAR received all scheduled interest payments in April.Overall, the stock has a unanimous Strong Buy analyst consensus rating, based on 4 reviews. The share price, 15.20, is an attractive point of entry for an equity with a 20.63 average price target; that indicates room for 36 upside growth this year.
