Your bull for holding companies.
DeinStier tracks the premium or discount to net asset value of holding companies like Berkshire Hathaway, Investor AB and Pershing Square, next to your whole portfolio, in one terminal built for long-term owners.
JOIN THE PRIVATE BETA iOS, Android and web. Early access is invite-only.
One terminal for the whole portfolio.
Built by an investor with a concentrated, long-term portfolio, for the same kind of investor.
Everything you own, in one table
Stocks, compounders, gold and silver, crypto straight from your Bitpanda wallets, cash, and statement-valued positions like bank bonds, with live prices in euros.
Premium and discount to NAV
Daily NAV estimates for holding companies, converted to one currency, with staleness flags so you know when an input needs a refresh.
History you can interrogate
Line, area, weekly candles, drawdown and daily returns, with a crosshair to read any day and period stats: return, max drawdown, volatility.
Targets, not noise
Set your own class targets and a drift band. You only get a rebalancing suggestion when a class moves outside it, plus a daily email brief.
Two styles. Tap the badge to switch.
Amber terminal or the neon of the bull — same screens, your pick. Shown with a demo portfolio.
