Stocks hit all-time highs yet again this past week. It is amazing that the investment community keeps hearing that the bull market has migrated to a stock picker’s market from a raging bull market. This is a climate in which investors will still look for gains, but they will be selective in their picks to avoid getting caught in bad stocks. 24/7 Wall St. reviews dozens of analyst upgrades and downgrades each day of the week, hunting for new ideas of stocks to buy and stocks to sell or avoid. As it turns out, there are almost always some hidden gems in the low-priced stocks trading under $10 and under $5 for their share prices.

What really stands out in this group of stocks is that in many cases the analysts are calling for the shares to double.

24/7 Wall St. does have a warning here for investors to keep in mind. Low-priced and small-cap stocks generally come with the most risk of all stocks in the market. If you want to see proof of this, consider that as of Friday there were only four stocks in the S&P 500 index trading under $10. Three were above $9.50, and only one of the S&P 500 members was trading under $9.

Another risk test here is that most stocks under $10 would also fail the “widows and orphans” suitability test, a term that brokers and financial advisors have to consider when it comes to ethics and suitability of investments for their clients. In short, small-cap and low-priced stocks can have risks that are way above average.

Last weekend’s stocks under $10 included eight picks, including FuelCell Energy, Halcon Resources, Harmony Gold Mining, Office Depot and more.

We have found 12 appropriate analyst calls from this past week that called for potentially huge upside in stocks under $10, plus there was one runner-up as a near-miss. We have listed what the analyst calls were and given the price targets if available.

These were the top analyst calls of the stocks trading under $10 for the week of June 2 to June 6.
