Frequently Asked Questions
Everything you need to know about Tefaster and Turkish mutual funds.
TEFAS & Mutual Funds
TEFAS (Turkish Electronic Fund Distribution Platform) is the official platform managed by Takasbank where all Turkish mutual funds are distributed and traded. It provides a standardized marketplace for over 2,300 funds from dozens of portfolio management companies.
Turkish TEFAS funds include equity funds (hisse senedi fonu), fixed-income funds (borçlanma araçları fonu), money market funds (para piyasası fonu), gold/commodity funds, mixed funds, and exchange-traded funds (ETFs). Each has different risk and return profiles.
Turkish mutual funds are priced once per trading day. The net asset value (NAV) per unit — called birim pay değeri — is calculated at market close and published on TEFAS. Purchases and sales submitted on a given day are settled at the next trading day's NAV.
NAV (Net Asset Value) is the total market value of a fund's assets minus its liabilities, divided by the number of outstanding units. It represents the price per unit of the fund and is recalculated every trading day.
All Turkish mutual funds are regulated by the Capital Markets Board of Turkey (SPK) and distributed via TEFAS. While this provides regulatory oversight, all investments carry risk. Tefaster is a tracking tool and does not provide investment advice.
Using Tefaster
After logging in, navigate to the Portfolio section and click 'New Portfolio'. Give it a name (e.g., 'Retirement', 'Short-term'), then add transactions to it. You can create multiple portfolios to keep different strategies separate.
Open a portfolio, click 'Add Transaction', search for the fund by name or code, enter the date, number of units (pay adedi), and the price per unit (birim pay değeri) from your broker confirmation. Select 'Buy' or 'Sell' and save.
A fund (fon) is the financial product managed by a portfolio company — for example, AK Portföy Hisse Senedi Fonu (AKH). A portfolio in Tefaster is your personal collection of transactions across one or more funds. You own units in funds; Tefaster organizes those holdings into portfolios.
Yes. You can create as many portfolios as you need. The dashboard shows an aggregated view across all portfolios, while the Portfolio section lets you drill into each one individually.
The fund detail page shows the historical NAV chart along with simple return and CAGR (Compound Annual Growth Rate) over selectable time periods. Short periods (under 1 year) show simple return only; longer periods show both.
Data & Accuracy
Fund prices are fetched automatically from TEFAS every day at 12:00 PM Turkey time (UTC+3). Exchange rates from the Turkish Central Bank (TCMB) and commodity prices are synced at the same time.
TEFAS funds do not trade on weekends or Turkish public holidays. When no price is available for a given date, Tefaster automatically looks back up to 7 calendar days to find the most recent trading day price. This ensures your portfolio value is always calculated correctly.
All fund prices are sourced directly from TEFAS via the official tefas-crawler library. Prices reflect the official NAV published by Turkish portfolio management companies and are the same values used for actual fund transactions.
Exchange rates (e.g., USD/TRY) come from the Turkish Central Bank (TCMB) official data feed. They are synced daily alongside fund prices and are used for fund comparison in the market data section.
Importing from MKK
MKK (Merkezi Kayıt Kuruluşu) is Turkey's central securities depository — the official institution that records all securities ownership in Turkey. To download your fund transaction history: log in at mkk.com.tr, navigate to Yatırımcı Girişi → Hesap Hareketleri, select your date range, and click the Excel button to download a .xls file.
Go to the Transactions page and click the 'Import from MKK' button. Upload the .xls file you downloaded from mkk.com.tr and select which portfolio the transactions should be added to. Fund purchases (fon alış) are imported as BUY transactions and fund sales (fon satış) as SELL. Blocking rows (blokaja alma / blokaj çözme) are skipped automatically.
Nothing — the import is idempotent. Each transaction is stored with a unique import reference derived from the fund's ISIN code, transaction timestamp, type, and unit count. Re-uploading the same file or an overlapping date range will not create duplicate transactions.
