The S&P/ASX 200 Index (ASX: XJO) experienced a downturn this week, declining 1.8% by Friday afternoon. The market's trajectory shifted following the Reserve Bank's announcement of a cash rate increase on Tuesday.

Despite the prevailing investor uncertainty, several ASX 200 stocks continue to attract significant analyst interest.

Highlighted below are four ASX 200 stocks forecast to achieve further gains of 70% to 80%, or more, this year.

Iperionx Ltd (ASX: IPX)

Iperionx, a company specializing in titanium metal and critical materials, was a top performer on the ASX 200 in January. The firm recently secured a prototype purchase order from American Rheinmetall valued at US$300,000. Additionally, Iperionx confirmed plans to scale up production, aiming to become the leading and most cost-effective titanium powder producer in the United States. Analysts maintain a bullish outlook on the stock, with a consensus strong buy rating. The highest price target of $11.03 suggests a potential upside of 83.76% from current levels.

ARB Corp Ltd (ASX: ARB)

ARB shares faced significant pressure late last month after the 4WD accessories manufacturer released its half-year trading update. The company reported a 1% decline in unaudited sales revenue and a 1.7% drop in aftermarket sales compared to the previous period. However, with the stock now perceived to be trading below its fair value, analysts anticipate a recovery this year. The maximum price target of $42.25 implies a potential increase of 73.44% from the current share price.

Capricorn Metals Ltd (ASX: CMM)

Capricorn Metals reported record cash flow and production for the second quarter of FY26. The ASX 200 gold miner also benefited from the recent rally in gold prices. With expansion plans underway, the company is well-positioned to capitalize on an expected rise in gold demand this year. Analyst sentiment is positive. A peak price target of $24 indicates a potential 81.75% upside.

Generation Development Group Ltd (ASX: GDG)

Generation Development Group delivered consistently strong financial results and earnings growth throughout 2025. Its return on equity and earnings growth have exceeded the industry average over the past year. The company announced record earnings and fund inflows for the December quarter last month, with the strong performance expected to continue into 2026. Analysts are highly optimistic about this financial stock, projecting a potential gain of up to 84.72% this year, with a target price of $8.46 per share.
