It is more or less understandable in industry and is associated with technological processes, but these regularities are also observed for the shares of the company's of technological and financial sectors. Bespoke Investment analyzed 20 stocks in the S&P 500 that have averaged a gain of more than 3% during the month of October over the past decade and also have seen positive returns at least 80% of the time. It is time to become acquainted with the best performers: Topping this month's list are shares of Google (GOOGL), which have averaged a gain of 14.5% during the month with positive returns 80% of the time. In addition to GOOGL, there are four other stocks from the Technology sector listed (AAPL, MA, ADBE, and ORCL). While a quarter of the stocks listed are from the Technology sector, the sector with the most representation is Financials with nearly half of the stocks (9) on the list. The two top performing stocks listed are NASDAQ OMX (NDAQ) and Intercontinental Exchange (ICE), which have averaged gains of 8.4% and 7.8%, respectively. Typically, increases in volatility are accompanied by a pickup in volumes, so the fact that two exchanges are near the top of the list makes perfect sense.
