. The hurricane, which took lives, stranded families and crippled utilities, touched industries ranging from refiners and retailers, to utilities, airlines, insurers and telecoms.
Meanwhile, in the Financial District of Lower Manhattan and across the Eastern Seaboard, rescue workers mounted a monumental effort to protect lives and repair basic infrastructure that spans nearly a dozen states as of Wednesday.
Major stock indices opened slightly higher only to fall, as investors digested the effect that Sandy may have on corporate earnings in coming quarters. Notably the technology sector underperformed, as a lock-up on hundreds of millions of

Those companies are concentrated in states like New York, New Jersey, Maryland, Connecticut, Pennsylvania and Delaware -- in Sandy's wide storm path.

Other sectors will also face challenges depending on how crippling Sandy proves to be. As of early Wednesday, four million households remain without power and reports indicate the death toll attributed to the hurricane is approaching 50.
