Recently, Clestica’s (TSX: CLS) share price surged a whopping 17% in just one day on July 29 after its earnings beat its guidance. The strong demand for networking switches from hyperscaler customers drove revenue up 21% year-over-year to $2.89 billion in the second quarter of 2025, beating its guidance of $2.72 billion. It also revised its 2025 guidance upwards to reflect the strong demand. If you have missed this growth rally, you need not worry. Canada has some cyclical and seasonal stocks that can generate high growth in a short period.
With the July 29 rally, Celestica stock is now in the oversold category, with a Relative Strength Index (RSI) of 80.2, indicating that a correction is likely. The RSI takes the 14-day average and determines the speed and magnitude of price changes. On a scale of 1 to 100, an RSI above 70 indicates that the share is overbought, and an RSI below 30 is underbought.

High-growth Canadian stocks to consider
Among seasonal growth stocks are e-commerce stocks like Shopify (TSX: SHOP) and Lightspeed Commerce. They tend to rally in the second half during the holiday season. Between the two, Shopify is a better growth stock as Lightspeed is still recovering from expensive acquisitions made in 2021.
Shopify
This time, the rally came early as Shopify stock jumped 57% from its April 2025 low and is just 6.3% below its 2024 holiday season peak. This makes one wonder if the stock has already ridden its seasonal rally. The RSI of 61 says otherwise. While the buying momentum has picked up, more growth is likely in November.
In 2024, Shopify stock surged 51% between early August and October and rallied another 57% to its holiday season peak in February 2025. This shift is because Shopify’s strategy to expand beyond small and medium businesses (SMB) to Enterprises, beyond North America to International markets, and beyond online to offline channels is normalizing seasonal growth. The company continued to grow its revenue by more than 20% for nine consecutive quarters.
You could consider buying the stock even now and enjoy another 40–50% holiday season rally till February. A good strategy is to buy the dip in the seasonally weak months of March and April, and sell in the February rally.
Hive Digital Technologies stock
Hive Digital Technologies (TSXV:HIVE) stock is cheap at the moment as it is in the next stage of artificial intelligence (AI) supply chain growth. Currently, hardware companies like Celestica are experiencing growth as hyperscalers and companies like Hive invest in building AI-ready data centres.
Hive is growing its capacity from six Exahash per second (EH/s) to 25 EH/s by December 2025. Its BUZZ High Performance Computing (HPC) segment saw 300 times revenue growth in the second quarter. The new capacity addition will help the company grow its HPC revenue and bring it on par with Bitcoin mining income. The capacity expansion could grow revenue fourfold and drive the stock price.
Hive stock is currently at an RSI of 49, which indicates balanced price momentum. Now is a good time to buy the stock before the momentum picks up. Early investing could help you ride the rally and double your investment, given the stock’s high volatility.
Final thoughts
Choosing the right stock can make a difference in your investment returns. Investing is only the first step. You should monitor returns on your investment periodically to determine whether to hold or sell a stock.
