It's shaping up to be a very decent Thursday session for ASX 200 stocks today. At the time of writing, the S&P/ASX 200 Index (ASX: XJO) is up by 0.2% at just over 8,550 points after hitting a new all-time record high of 8,575.2 points just before midday today.

As one would expect on a new record day for the broader market, a flurry of ASX 200 stocks have also hit new 52-week highs.

Six ASX 200 stocks at new 52-week highs this Friday

Here are the six ASX 200 stocks that have just clocked new 52-week highs this Thursday:

What can we learn from these new 52-week highs?

Many of these ASX 200 shares are the usual suspects that we've already seen clock new highs this week.

Once more, three out of the four big ASX 200 bank stocks are at new highs today in the aftermath of CBA's latest earnings. CBA has again hit a new all-time record, while both Westpac and NAB are at multi-year highs (18 years in NAB's case). You'd have to be feeling something for ANZ Group Holdings Ltd (ASX: ANZ) shares at this point.

Wesfarmers is also at a new record high today. Perhaps investors are anticipating a strong earnings report when the ASX 200 conglomerate shows its hand next week.

ASX 200 gaming stock Aristocrat Leisure seems to be on the move today to its new record without any major catalysts. A possible explanation is the positive broker report we covered earlier this week. Bell Potter gave Aristocrat shares a 'buy' rating, alongside a 12-month share price target of $83. If realised, that would see Aristocrat hit even more new highs in the months ahead.

Finally, it's worth mentioning the iShares ASX 200 ETF. Although this index fund is not technically an ASX 200 stock, it does track the ASX 200 Index. As such, I thought it was worth mentioning on our list. Of course, with the ASX 200 Index itself at a new high today, it's no surprise to see this index-tracking ETF follow suit.
