Crude-oil futures reversed their earlier losses Tuesday, following strength in U.S. stock markets as financial companies led the market higher. Crude for May delivery was last up 36 cents, or 0.8%, at $46.24 a barrel. The contract had fallen to as low as $43.83 earlier. "Oil prices appear to be using the equity markets as an indicator," said Shane Wisdom, president at futures trading firm Wisdom Financial Inc.
