Want to see just how much pressure the stock market is under? Got a buck? There are now 359 stocks trading for under $1 a share – the highest in more than 20 years. The number of stocks currently trading on a major U.S. exchange for less $1 a share has jumped 38% this year and is up 420% from five years ago, according to a USA TODAY analysis of data from S&P Global Market Intelligence. Seeing such a rapid jump in the number of penny stocks shows just how pummeled the market has become. This analysis is limited to stocks currently trading on a major U.S. exchange – thus omits stocks that have been delisted or bought over the years.
