Struck by two things here. First, and most obvious, check before you buy, people. This is your hard-earned money. If you heard about Google buying Nest and just can’t resist, make sure you know the proper stock symbol before you hit add-to-cart.
Second, and most interesting to me, people were rewarded for this mistake, at least until the roller coaster went back down again. Apparently, this sort of confusion happens periodically. Nestor, Inc. trades over-the-counter under the symbol NEST. The question is, did an actual savvy investor spot this name confusion and buy Nestor as soon as the Nest acquisition was announced, then sell at the top?
