SK Hynix Inc.’s shares slid after record quarterly results failed to impress investors grappling with stagnant smartphone demand and questions about AI spending in 2025.

The South Korean memory-chip maker reported record quarterly and annual results after stronger-than-expected earnings for the final quarter of 2024 on robust chip demand.

Shares of Nvidia (NASDAQ: NVDA) and Vistra (NYSE: VST) have surged 860% and 700%, respectively, since the beginning of 2023. Both companies have benefited from the artificial intelligence (AI) boom despite operating in very different parts of the economy.

Nvidia is once again the most valuable U.S. company, outranking Apple for the first time since late November. The chip maker ended Tuesday with a market capitalization of $3.449 trillion, according to Dow Jones Market Data.

Now that it's the world's most valuable company, some investors might believe the time to buy Nvidia has already passed, but these developments show that's not the case.

Several of Nvidia's partners have stated that the RTX 5090 and RTX 5080 will likely only be available by Mid -February

Nvidia's RTX 5090 offers 21760 CUDA cores as part of its Blackwell architecture offerings, in addition to 32GB of GDDR7 memory with a peak bandwidth of 1792 GB/s. This is a massive upgrade over the 16,384 cores and 1008 GB/s bandwidth available to the 24GB of GDDR6X that the RTX 4090 currently hosts.

The ETF industry’s upstart-in-chief is back with another roll of the new-product dice — this time betting on a game-changing expansion of Wall Street’s zero-day options boom.

Recently, the stock has fallen around 10% from its all-time highs, which some may consider a buying opportunity. However, Nvidia has done so well over the past few years that other investors are concerned that it may have reached its top.
