Fortescue Ltd (ASX: FMG) shares have fallen to a new 52-week low on Tuesday.
At the time of writing, the Fortescue share price is down 2.37% to $17.28 after briefly touching $17.10 earlier this morning.
There's a pretty simple explanation behind much of today's fall. Fortescue is trading ex-dividend for its 46-cent fully franked final dividend, which is due to be paid later this month.
Still, today's move continues what has been a difficult year for shareholders.
Fortescue shares are now down around 21% since the start of 2026 and have fallen roughly 6.7% over the past month.
So, with the shares back at their lowest level in a year, is this starting to look like a buying opportunity?

A rough few months
Fortescue shares were trading above $22 in late May before beginning their latest slide.
The stock has struggled to regain momentum since then and entered September close to the bottom of its 52-week range.
Today's ex-dividend move needs to be kept in context. The shares closed at $17.70 yesterday and investors buying from today will no longer receive the 46-cent final dividend.
Looking beyond today's price swing, Fortescue recently reported FY26 underlying EBITDA of US$8.6 billion, up 9%, and underlying net profit rose 9% to US$3.5 billion.
Free cash flow increased 25% to US$3.2 billion, while iron ore shipments reached a record 201.3 million tonnes.
What do brokers think?
Despite the weaker share price, brokers remain fairly cautious.
According to TipRanks, the average 12-month price target across 11 analysts is $17.95. That's only around 4% above the current Fortescue share price.
There are currently 2 'buy' ratings, 6 'holds' and 3 'sells'.
Morgan Stanley is one of the more bearish brokers. It reiterated its 'sell' rating on Tuesday with a $15.45 price target, implying downside of around 11% from current levels.
At the other end, Macquarie has a 'buy' rating and $20 target, while Ord Minnett is also positive with a $19.50 target.
Is it time to buy Fortescue shares?
The falling share price has certainly made Fortescue look cheaper than it did a few months ago.
The company paid $1.08 per share in fully franked dividends across FY26. Based on the current share price, that represents a trailing dividend yield of around 6.3%.
But brokers don't see a huge amount of upside on average, and the shares have remained in a clear downtrend since May.
That leaves investors with a mixed picture. The shares are cheaper and the dividend yield looks decent, but brokers are hardly rushing to call the stock a bargain.
A lot will depend on whether Fortescue can keep producing strong cash flow from here.
