The S&P/ASX 200 Index (ASX: XJO) had a strange August, setting a record closing high on 6 August before finishing the month up just 1.1%.
Underneath that flat number, some large companies were taken apart.
Five ASX 200 shares fell between 17% and 23%.
What makes three of these companies interesting is that they were still able to grow revenue.
The market was not punishing failure so much as repricing expectations.

Why these ASX 200 shares fell so hard
All three stocks reported in August and all three fell heavily on the day.
None of them missed on revenue.
Each was marked down on what came next, whether that was a cautious start to FY27, a margin moving the wrong way, or costs growing faster than the top line.
That is a very different problem from a broken business, which is why they are worth a second look.
1. JB Hi-Fi (ASX: JBH)
JB Hi-Fi closed Monday at $66.57, down 42.58% over twelve months and within a few cents of its 52-week low of $66.02.
The FY26 result delivered record revenue of $11.06 billion, up 4.8%, with net profit after tax rising 6% to $489.9 million.
The shares then suffered their worst day on record, falling 12.3%, and ended August down 18.3%.
The damage came from a single line in the trading update.
Comparable sales for JB Hi-Fi Australia fell 1.4% in July.
That is the first real sign the consumer is cracking, and with home values falling and a rate rise possibly ahead, it is a fair thing to worry about.
The offset is the valuation, with the shares now on a price-to-earnings ratio of 15.02 and a fully franked yield of 5.02%.
2. Life360 Inc (ASX: 360)
Life360 fell 21% across August and closed Monday at $20.17.
The twelve-month decline is 55.77%, which is brutal for a company still growing this quickly.
Second-quarter revenue rose 38% to US$159 million and adjusted EBITDA jumped 53% to US$31.1 million.
The catch sat below those numbers.
Net income fell 17.8% to US$5.1 million, and the net income margin halved to 3% from 6%.
Investors had been paying for a business that was supposed to scale into profitability, and the margin went backwards instead.
At $20.17 against a 52-week high of $55.87, a great deal of optimism has already been stripped out of the price.
3. Generation Development Group Ltd (ASX: GDG)
Generation Development Group was August's worst performer, falling 22.6%, and it continued to decline on Monday, closing at $3.06.
That is a fresh 52-week low and a decline of 51.43% across the year.
FY26 revenue rose 23% to $178.7 million and funds under management jumped 37% to $46.5 billion.
Underlying net profit after tax climbed 21% to $40.7 million.
Statutory net profit fell 10% to $31.9 million, because operating expenses grew 26% and comfortably outpaced revenue.
The risk in buying beaten-down ASX 200 shares
Cheap shares can get cheaper, and all three have proven this fact repeatedly.
Investors sometimes falling into the value trap, buying cheap businesses without assessing the reasons why they are cheap.
Foolish takeaway
Of the three, JB Hi-Fi has the clearest valuation support and the most obvious risk sitting right in front of it.
Life360 has the strongest growth and the least proven path to profitability.
Generation Development owns the best asset in a $46.5 billion funds book but has the worst cost discipline.
I would want to see one more result from each before committing capital.
For patient investors, August produced a list of beaten-down ASX 200 shares that are cheaper than they were. The question remains whether they can recover.
