24/7 Wall St.

Stocks were indicated lower on Wednesday, after big gains on Tuesday. The stock market is still fighting for a positive 2015. Still, the trend that has prevailed for over four years now is that investors have bought every single market pullback — without a single 10% formal pullback in all three major U.S. equity indexes.

24/7 Wall St. reviews dozens of analyst research reports each morning of the week to find new investing and trading ideas for its readers. Some of these analyst reports cover stocks to buy, and other analyst calls cover stocks to sell or avoid.

As a reminder, 14 strategists are calling for a positive, but mixed, S&P 500 performance in 2016.

These are this Wednesday’s top analyst calls.

Intel Corp. (NASDAQ: INTC) was reiterated as Buy at Needham, and the firm raised its price target to $38.00 from $37.00 (versus a $35.44 prior close). Intel has a consensus analyst price target of $36.19 and a 52-week trading range of $24.87 to $37.49.

Petrochina Co. Ltd. (NYSE: PTR) was reiterated as Buy at Jefferies, but its targets were in Hong Kong and implied close to 63% upside. The call is after selling gas assets and likely plans to sell more in 2016.
