Investor Stephanie Link shared her three investing plays on "Halftime Report" as the markets rebounded, including a regional banking stock that she believes has potential. She highlighted Truist Financial, which is currently trading at 0.9 times its book value, as one of her preferred plays. She also mentioned the potential of deregulation as another catalyst for increased bank buybacks and dividends. Despite the potential impact of the proposed legislation to ban sports betting on prediction markets, Link stood by her ownership of Las Vegas Sands, despite acknowledging its potential impact on casino stocks. The iShares MSCI Brazil ETF (1919) is up 16% this year and will be a significant player in the emerging power demand of the country.
