NEW YORK ( TheStreet) -- Bank stocks remain one of the top performing industries over the past 12 months and year to date, but some bank stocks could be jolted by positive or negative surprises in their earnings reports over the next two weeks.On Sept. 26 I wrote Don't Bank on Bank Stocks, Just Trade Them, and today I update my profiles for 14 banks that report quarterly results between Oct. 15 and Oct. 23. Included in these profiles are my new monthly and quarterly value levels, pivots and risky levels that should be used to revise your "buy-and-trade" strategies for these banks. All 14 of these stocks are components of the PHLX KBW Banking Index ( BKX), which is up 56.4% since bottoming in October 2011, and is up 29.3% so far in 2012, while the S&P 500 is up 33.3% since last October and 13.9% year to date. The BKX has been technically overbought on its weekly chart since the week of Sept. 7, and the finance sector is overvalued by 12.6% according to www.ValuEngine.com. The daily chart for the BKX (50.91) shows rising momentum with the 21-day, 50-day and 200-day simple moving averages at 50.45, 48.49 and 46.13. My quarterly and annual value levels are 47.55 and 42.98 with monthly and weekly risky levels at 51.89 and 52.30. Note the double-top at 52.11 on Sept. 14 and 52.04 on Oct. 5.
