The S&P/ASX 200 (INDEXASX: ^AXJO) (ASX: XJO) fell 1% to 4,993 points today, reversing much of Monday’s gains after the oil price crashed overnight and the Reserve Bank of Australia elected to leave interest rates on hold.

Here are some of the more notable fallers today:

Domino’s Pizza Enterprises Ltd. (ASX: DMP) fell 1.7% to $59.58 after shares hit an all-time high of $60.94 in trade yesterday. Buyers look to be running out of enthusiasm, as the company trades at a staggering 80 times last year’s earnings – unusually high even for fast-growing businesses. This may also be the pullback that the share price needs.

Many investors are interested in the stock, which has grown 867% in the past five years. However, I would warn buyers to do further research on how much future growth is already factored into the share price, and whether the company can continue growing at its previous rate.

1-Page Ltd (ASX: 1PG) lost 5.6% to $3.20 in continuing uncertainty over what this unprofitable company is actually worth. 1-Page recently announced another A$1.39m in annualised contract revenue, which is not a large increase for a company valued at over $400m by market cap. Despite a recent decline in buyer enthusiasm, 1-Page shares are still up 220% for the year.

Rent.com.au Ltd (ASX: RNT) crashed 12% to $0.22, furthering the decline which began after the company released its quarterly report to the market last Friday. It appears investors were disappointed with the company’s growth, despite it posting a 47% increase in site traffic and a significant increase in the number of listings. Cash outflow continues and the company appears to have around 9 months of operations remaining at its current cash flow levels before it must raise more funds.

Rent.com.au shares are now only marginally above the price they listed at, which may be a ‘second bite at the apple’ for interested investors.

Magellan Financial Group Ltd (ASX: MFG) dropped 5.3% to $21.92 on no news today, taking its fall to 19.5% in the past month. Curiously enough, the fall comes despite portfolio manager and CEO Hamish Douglass buying half a million shares in subsidiary fund Magellan Global Equities Fund (Currency Hedged) (ASX: MHG) in the past fortnight. Fund managers tend to get sold off as markets fall – given much of their revenues are driven by the amount of funds under management.

Magellan Group as a whole has done very well for investors, returning 1,239% in the past five years according to Google Finance.
