When share prices fall 20% to 50% in a year, it's easy to assume something is fundamentally broken. Sometimes that's true. But other times, the market overshoots, pricing in far more bad news than actually eventuates.
Right now, I think there are a few ASX shares sitting firmly in that second camp. They've been hit by a mix of cyclical headwinds, short-term disappointments, and weak sentiment, but their long-term investment cases remain intact.
These are three cheap ASX shares I think are strong buys this month.

Cochlear Ltd (ASX: COH)
Cochlear is not a stock that often looks cheap, which is why its share price decline over the past year stands out.
The weakness has been driven by slower-than-expected growth in its core hearing implant business, cost pressures, and cautious sentiment around margins. None of that is ideal, but it's also not structural.
Cochlear remains the global leader in implantable hearing solutions, operating in a market with high barriers to entry and long product lifecycles. Its installed base continues to grow, supporting recurring revenue from upgrades, accessories, and services over time.
Demand for hearing solutions is also supported by powerful demographic tailwinds. Ageing populations don't disappear just because growth is softer for a year or two. With expectations now far lower than they were previously, I think the risk-reward has become much more attractive.
Treasury Wine Estates Ltd (ASX: TWE)
Treasury Wine Estates has been one of the hardest-hit large-cap consumer names on the ASX, with its share price down sharply over the past 12 months.
The reasons are well understood. Softer demand for premium wine, cost-of-living pressures, and challenges across key markets have weighed heavily on earnings and sentiment. On top of that, the company has been working through portfolio changes and operational resets, which has created near-term uncertainty.
What interests me now is how much pessimism is already reflected in the share price. Treasury Wine still owns a portfolio of globally recognised brands, generates solid cash flow through the cycle, and is expected to see dividends recover as conditions normalise.
This looks like a classic case of a quality consumer business being priced for prolonged weakness. If demand stabilises even modestly, the upside with this ASX share could surprise.
James Hardie Industries Plc (ASX: JHX)
James Hardie Industries is another example of a high-quality ASX share caught in a cyclical downturn.
The housing slowdown in the US and other key markets has pressured volumes and margins, which has flowed directly into the share price. As a result, the stock is now trading well below where it sat a year ago.
However, James Hardie's competitive position has not changed. It remains the market leader in fibre cement products, with strong brand recognition, pricing power, and exposure to long-term renovation and repair demand, not just new builds.
Housing cycles turn. When they do, businesses with scale and strong distribution networks tend to recover faster and more profitably than smaller competitors. That's why I see current weakness as an opportunity rather than a reason to stay away.
Foolish takeaway
Cheap doesn't always mean attractive, but when quality businesses fall 20% to 50% in a year, it's worth paying attention.
Cochlear, Treasury Wine Estates, and James Hardie have all been hit by short-term headwinds and negative sentiment. In my view, the market has become too focused on what's gone wrong recently and not focused enough on what these businesses can earn over the long run.
For investors willing to look beyond the next quarter or two, I think these cheap ASX shares offer compelling opportunities this month.
