Stock Price Alerts on WhatsApp, Push & Email: Never Miss a Market Move

The Cost of Missing a Market Move

A stock in your portfolio drops 8% in a single session. By the time you check your phone at lunch, it's recovered 3% — and you missed the buying opportunity. Or worse: a position you've been meaning to sell finally hits your target price while you're in a meeting. Minutes later, it retreats. You had the plan. You just didn't have the alert.

trefolio delivers price alerts where you actually see them — WhatsApp, browser push notifications, and email. Set your thresholds once, and trefolio watches the market for you.

Multi-Channel Alerts: WhatsApp, Push & Email

Most alert systems are limited to email or in-app notifications — channels you might not check in real time. trefolio supports three channels:

• WhatsApp — instant messages to your phone. No app to install, no notifications to miss. This is the fastest way to get alerted during market hours.
• Browser push notifications — alerts pop up on your desktop or mobile even when trefolio isn't open. Works on Chrome, Firefox, Safari, and Edge.
• Email — for a persistent record of every triggered alert. Great for end-of-day review.

You can enable one channel or all three. WhatsApp is the standout — most European investors have it open all day, making it the lowest-latency option.

Percentage-Based Price Triggers

trefolio supports two types of percentage-based alerts:

• Daily change — notify when a stock moves more than X% in a single session (e.g., "Alert me if ASML drops more than 5% today")
• Versus purchase price — notify when a stock moves X% from your cost basis (e.g., "Alert me if my NVIDIA position is up 50% from my average buy price")

This is more flexible than fixed price alerts. Percentage-based triggers adjust with the stock's price, so you don't need to recalculate targets manually.

Portfolio-Wide Alerts

Don't just monitor individual stocks — monitor your entire portfolio. Set a portfolio-wide alert to notify you when your total portfolio value changes by more than a specified percentage in a day. This catches broad market moves (like index-level sell-offs) without requiring an alert on every single holding.

Big Market Move Alerts

trefolio also watches major indices. When the S&P 500, Nasdaq, or Euro Stoxx 50 moves more than 4% in a session, you get an automatic alert — even without setting one. These rare, high-impact moves are the ones that matter most, and trefolio makes sure you know about them.

Step-by-Step: Setting Up Your First Alert

1. Go to your Profile page and enable your preferred notification channels (WhatsApp, push, email).
2. Navigate to any stock in your portfolio or watchlist.
3. Click Set Alert and choose your trigger type (daily change or vs. purchase price).
4. Set your percentage threshold.
5. Save — trefolio monitors the stock and notifies you when the condition is met.
