Lithium price pressure and Mizuho target cut

According to The Rio Times in a summary published on September 19, 2026, Albemarle ended at USD 110.91 on its New York listing after falling 3.60 percent in the latest session, leaving the stock 5.62 percent lower for the week in step with another slide in China lithium prices.

Valuation and recent performance signals

In a valuation note dated September 18, 2026, GuruFocus highlighted that Albemarle shares fell 3.6 percent to USD 110.91 and trade between a 52-week low of USD 79.30 and a 52-week high of USD 221.00, implying the current price sits around 40 percent above the lower end of that range but roughly 50 percent below the peak.

The same analysis noted that Albemarle’s GF Value estimate stands at USD 80.42, meaning the stock is about 37.9 percent above that intrinsic value indicator at its current price of USD 110.91, a gap that underpins the argument that the shares remain significantly overvalued despite the recent pullback.

According to Zacks on September 18, 2026, Albemarle closed the latest session at USD 110.91, down 3.6 percent on the day, while the S&P 500 gained 0.17 percent, and the stock has lost 14.26 percent over the past month compared with a 0.24 percent decline for the Basic Materials sector and a 1.29 percent drop for the index.

Zacks also pointed out that Albemarle trades at a forward price-to-earnings ratio of 10.1 as of that report, a discount to the industry’s average forward P/E of 16.69, and carries a price/earnings-to-growth (PEG) ratio of 0.67, suggesting that despite cyclical headwinds the current valuation embeds lower multiples than peers when adjusted for expected growth.

Position in the lithium producer peer group

The Rio Times compared Albemarle with Chilean peer SQM in its September 19, 2026 lithium markets roundup, noting that SQM’s New York listing closed at USD 67.72 after a 5.68 percent drop, while Albemarle fell 3.60 percent to USD 110.91, with both producers pressured by renewed downside in China lithium prices but Albemarle showing a slightly smaller one-day decline.

In a peer comparison on September 19, 2026, Pluang listed Albemarle at a share price of USD 110.91 with a market capitalization of USD 13.09 billion, contrasted with a USD 85.52 share price and USD 98.38 billion market capitalization for regulated utility Southern Company, underlining how much smaller Albemarle is than large defensive peers despite its central role in the lithium supply chain.

Pluang’s snapshot added that Albemarle shares were down 29 percent over the last six months, a steeper slide than broader equities and utilities, as lithium price weakness weighs on sentiment even though recent earnings beats and a new chief executive appointment have provided some optimism about execution and strategic direction.
