In technology, there are very few themes that are investible, said Cramer, although individual companies might be.
According to Cramer the entire sector is a dangerous place because largely it can't escape the woes vexing the PC market, which is facing declining sales as tablets cannibalize the market.
Barclays Capital's hardware analyst Ben Reitzes perhaps summed up sentiment on the Street best late last year when he cut his outlook for the sector through 2016.
"It can no longer be assumed that the PC market can remain in the range of 350 million units a year - and we argue that the PC replacement cycle is in the process of being elongated by 1-2 years, resulting in the loss of 50-100 million units in annualized demand by 2015," he wrote.
