Several Wall Street analysts gave positive comments on individual stocks on Friday, and two of the most interesting calls were on Cintas (NASDAQ: CTAS) and Alcoa (NYSE: AA). Market participants aren't sure how to handle the current inflationary pressures hitting the economy, but central bank policymakers show no signs of changing their strategy in managing monetary policy. Barclays and Credit Suisse boosted their price targets on the stock, while analysts at William Blair argued that Thursday's brief sell-off following the company's fiscal fourth-quarter earnings report offered a rare bargain opportunity.
