Gains in semiconductor company Nvidia Corp. (NVDA - Get Report)  inspired a rally across chipmakers, though the rest of the tech sector sat it out. 

Nvidia reached an all-time high earlier on Monday, Sept. 18, and inspired gains in fellow chipmakers after a bullish note from Bank of America analyst Vivek Arya. Arya raised the firm's price target to $210, up from $185. The new price target implies a 17% upside to the stock's closing price on Friday, Sept. 15. 

In a note, Arya said Nvidia has an "underappreciated transformation from a traditional PC graphics-chip vendor into a supplier into high-end gaming, enterprise graphics, cloud, accelerated computing and automotive markets." Arya is also confident Nvidia can dominate the emerging $30 billion artificial-intelligence chip market. 

Other chipmakers including Micron Technology Inc. (MU - Get Report) , Taiwan Semiconductor Manufacturing Co. Ltd. (TSM - Get Report) , Analog Devices Inc. (ADI - Get Report) , Semiconductor Manufacturing International (SMI) , and Texas Instruments Inc. (TXN - Get Report)  were also higher.
