Wesfarmers Ltd (ASX: WES) is the kind of ASX share that can be hard to judge.
The business quality is obvious. The price is the harder part.
So, should investors buy, hold, or sell Wesfarmers shares today?

Why selling feels too harsh
I would find it difficult to call Wesfarmers a sell.
This is one of the strongest long-term operators on the ASX, and I think that still counts for a lot.
Bunnings remains one of the best retail businesses in Australia. It has strong customer trust, a dominant market position, and a role in home improvement that is hard for rivals to replicate at scale.
Kmart is also a much better business than it was many years ago. Its value focus has made it highly relevant at a time when households are watching spending more carefully.
I also like that Wesfarmers keeps looking for ways to make the group stronger. Health, data, digital initiatives, OnePass, and other growth options may not transform the business overnight, but they give the company more ways to deepen customer relationships and reinvest over time.
That is the part of Wesfarmers I find most appealing. It is not just a collection of retail brands. It is a management culture that has demonstrated a long-term ability to improve assets, make disciplined decisions, and allocate capital to better opportunities.
Why buying aggressively is harder
The issue is valuation. Wesfarmers shares are trading at around $91.67 at the time of writing, which is close to the upper end of their yearly range of $70.80 to $95.18.
According to CommSec consensus estimates, Wesfarmers is expected to generate earnings per share of $2.55 in FY26 and $2.74 in FY27.
That puts the stock on a price-to-earnings (P/E) ratio of around 36 times FY26 earnings and 33.5 times FY27 earnings.
I can justify a premium for Wesfarmers. I have much more trouble justifying any price.
At this level, investors are paying upfront for a lot of future success. That can work if Bunnings stays strong, Kmart keeps performing, the health division improves, and newer digital initiatives add value.
But the starting point is important for future returns. When a high-quality company is priced this fully, even a good business can deliver more modest shareholder returns if earnings growth is only steady rather than exceptional.
The forecast dividend yield also does not make the valuation look cheap. CommSec estimates dividends per share of $2.16 in FY26 and $2.33 in FY27, implying forward yields of around 2.4% and 2.5%.
That income is attractive enough, but it is not the reason I would own Wesfarmers.
My verdict
My verdict is hold. If I already owned Wesfarmers shares, I would be happy to keep them. The company has too many strengths for me to want to step away just because the valuation looks full.
For new money, I would be more patient. I could understand buying a small amount now for a long-term position, especially for investors who like building into quality companies over time.
But I would prefer to buy more meaningfully during a pullback.
Foolish Takeaway
Wesfarmers remains one of the ASX businesses I would trust to keep improving over the long term.
The company has strong brands, experienced management, and several areas where it can keep reinvesting for growth.
The share price already reflects a lot of that quality. That is why I would hold Wesfarmers shares today. I would keep it high on my long-term watchlist, stay patient, and look for a better chance to buy more when the market offers one.
