Stocks to watch as November starts: Fitbit (FIT) - the fitness tracking company agreed to a disappointing deal to sell the company for $7.35 per share in cash to Google (GOOG). The stock is being sold for an EV/S multiple of 1x. The valuations is so cheap that a possibility exists that another buyer will come out to raise this bid, but investors shouldn't bet on it. Pinterest (PINS) - clear example of a stock trading at an irrational valuation. Pinterest was up above $15 billion and the company raised guidance to revenues of $1.1 billion. Down 20% to a $10 billion market valuation doesn't leave the stock anymore appealing. Pinterest has some long term potential, but investors need to pay a reasonable price to make money here. So far the stock has held the lows from the IPO, but one should expect a lower range here. AbbVie (ABB) - the biopharma hiked the quarterly dividend 10% to $1.18. Despite the stock gains, the new dividend yield is still an incredible 5.8%. Keep holding the stock or buyout target Allergan (AGN). Disclosure: Long FIT, AGN
