Would selling significantly below market affect the value of a stock
Assuming you are executing your order on a registered exchange by a registered broker, your order will be filled at the best bid price available.  This is because brokers are legally obliged to get the best price available. For example, if the market is showing a bid of 49.99 and an offer of 50.01 and you submit an order to offer 1000 shares at 5.00, your order will be filled at 49.99.  This is assuming the existing bids are for enough shares to fill all of the 1000 shares being offered.  If the share you are offering lacks the necessary liquidity to fill the order - i.e., the 49.99 bid is for less than 1000 shares and the "level two" bids are not enough to fill the remaining shares, then the order would be posted in the market as an offer to sell the balance (1000 - shares filled at 49.99 and those filled at level two bids) at 5.00.   I'm pretty sure that the scenario you are describing would be described as market manipulation and it would be against the law.
