As has traditionally been the case, the financials sector is going to lead off the Q1 earnings season with reports this week from BlackRock on Thursday and Wells Fargo, PNC Bank, Citigroup and JPMorgan Chase on Friday. Morgan Stanley and Bank of America report during the first half of next week.The financials sector has seen its earnings expectations revised upward throughout the year so far. It's now expecting to see 20% year-over-year earnings growth, one of the highest comps in the market. With the tailwinds of future rate increases, corporate tax reform benefits and a forward P/E of around 13, this sector is a buy heading into earnings. ETFs to consider include the Vanguard Financials ETF (VFH), the Fidelity MSCI Financials ETF (FNCL) and the Financial Select Sector SPDR ETF (XLF).The question arises as to whether or not these anticipated results are already baked into stock prices. It may be, but I still expect this group to perform well by the end of next week.What do you think? Are you buying banks heading into earnings? Comment down below!
